TARGET=$(awk -F "PATH: " -vx=$IP ' $0 ~ x {print $2}' config_ip.cfg)
awk -F "PATH: "   #### -F in awk defines the field seprator whuch we want to makein any Input_file, so here we are mentioning it should be string "PATH: "
-vx=$IP           #### -v in awk is used for initializing a vatiable, so here we are creating a variable named named x whose value is equal to value f shell variable named $IP. Because in awk we can't mention variable's
                       value like shell so like this we could assign any shell's variable value to awk's variabe to make use of it in awk program.
' $0 ~ x          #### Mentioning a condition here if $0(current line) equals to value of variable named x(which we defines with -v explained as above), if this condition is TRUE then execute the following statements.
{print $2}'       #### printing the field 2nd of the current line in case above condition is TRUE.
config_ip.cfg     #### Mentioning the Input_file here which awk has to read and process whose name is config_ip.cfg here.
